Presentation Transcript

  1. Industrial Processes and Site Visits (02/26/2014) Ravenswood Power Plant

  2. Electrical power production and distribution in the US • Generation • Indian Point/Ravenswood • Transmission • High voltage transmission lines (>110 KV)to reduce energy loss during transmission- limited ability to store electricity • Substations (step up/step down) • Electric and Magnetic Fields (EMF) Radiation from power lines • Localized supply to customer • Varying safety and/or work related health issues for each segment

  3. National Power grid • Three regional grids with limited links Eastern/Western/Texas grids

  4. Safety training- Ravenswood • Learning management system • Software for the administration, documentation, tracking, delivery of electronic training to workers

  5. Ravenswood potential hazards • Noise • > 105 db. double protection required • Electrical • Arc flash • shocks • Slips/trips/falls • Confined spaces • Chemical exposure • LOTO • Asbestos • PCBs • Ergonomic/ repetitive stress/over exertion/awkward postures • Hot/cold environment (seasonal) • Shift work • 24/7

  6. Shiftwork • Shiftwork is anything other than a daylight work schedule-nights, evenings, extended work days, etc. • Circadian rhythm • Zeitgraber - environmental cues that synchronize biological systems to the light/dark cycle • Elevated BMI (reports of an association with Diabetes Mellitus), certain cancers or ulcers, accidents e.g. Exon Valdez, Challenger, automobile, medical. • Controls • Consistent scheduling, use of window shades, eliminate family/social interruptions at home, pre/post shift naps, caffeine, etc.

  7. Ravenswood

  8. Asbestos • US production stopped 2002 • We still import substantial amounts of asbestos • 2012 – 1060 tons • Primarily the Chlor-Alkali industry (chlorine and sodium hydroxide for chemical industry) and roofing industry

  9. Coal fired generators

  10. Protective clothing

  11. Confined spaces • Large enough for workers to enter and perform required tasks • A limited or restricted means for entry or exit • Not designed for continuous occupancy. • Permit required confined space • hazardous atmosphere, • sloping walls • potential to engulf, trap or asphyxiate an entrant • unguarded machinery • live wires • a potential for heat stress.

  12. Control of Hazardous Energy(LOTO) • Designed to prevent unexpected startup during repair, servicing or maintenance of machinery and equipment by removing sources of energy - electrical, chemical, hydraulic, gravitational, pneumatic, thermal etc. • Employers are required to have written LOTO procedures and • ID all potential energy sources including stored or residual sources • Provide site specific worker training • Locks are removed by the worker that put it on. • Exemptions • To de-energizing the equipment will cause a hazardous condition (life saving equipment) • It is impossible to do because of design or operational limitations.

  13. LOTO • Tags can use if you are unable to lock out the energy source • Required to demonstrate that a tag system will provide the equivalent level of protection as a lock • L’Oreal/Ravenswood • Two key system/other LOTO systems

  14. Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) • REACH – European Union regulatory system for chemicals (2007) • Requires registration of all chemicals manufactured or imported in EU with the European chemicals agency (143,000). • Manufacturers and importers are required to gather information on the properties of their chemicals to will allow safe handling and they must register the information in a central database • Requires sharing of information • Provides lists of hazardous chemicals • Substances of Very High Level of Concern (151) - carcinogens, mutagens, reproductive toxin, hormone interrupters • SVHCs placed on authorization list cannot be used unless granted an exemption • Substitute it now list (SIN) for chemicals of concern • Importers/manufacturers are required to assess risks to human health or the environment • Requires that chemical companies minimize animal testing • REACH eliminates requirements for types of testing on animals e.g. corrosive,

  15. What is a Job Hazard Analysis • A technique designed to identify hazards at the work site • Break the job down into it’s basic components • ID the hazards in each component • Develop controls for all of the recognized hazards • JHA focuses on the relationship between the worker, task, tools and the environment

  16. Prioritization of JHA at the work site • Jobs associated with the highest rate of injury, illness • Jobs associated with severe illness, injuries or catastrophic events • New operations • Complex procedures • Jobs in which a small error could lead to severe accidents or injuries
